T0 obll. whom it may concern:

Be it known that L'Josnrn L; MARINER, a: citizen *of the United States,residing at: Gold 9 HiIL'in-the county of-Jackson and State of Oregon,have invented a new and useful Hy' draulic Motor, of which the followingis a;

, specification.

ings.

This-invention relates more particularly to that type ofmotor popularlyknown as "rotary impact, wherein one or more streams of water aredirected by suitable nozzles:

against a rotary wheel.

One of the objects of the-inventionis to provide a novel constructionwherein the dis-- acharged water after having acted upon the.

wheel is directed away from the same, there-i by obviating frictionalresistance to a very; material degree.

Another object is to provide'an arrange-' Inent wherein the end thrustis obvi atedg and still another object is to provide a =motorthat. canbe easily dismembered and wherein the. various parts are readilyaccessible for repairi orrenewal; I

' An embodiment of the invention that is at. present considered thepreferable one is illus trated in the accompanying drawings, where-Figure 1 is a sectional view through the.

:motor. Fig. 2' is another sectional view taken-at rightangles to Fig.1.

Fig. 3 is a detail perspective view of a portion of the wheel. Fig. 4 isa detail sectional view taken; on the line 4; 4: of Fig. 1.

inner side. I

Arotary wheel 12 is secured to the shaft 8 and is locatedwithin thecasing, said wheel; having flat opposite sides and being provided: withperipheral spacedflanges 13 the router;

of the sections 16 are standing guard disks 18, ocated directly' ad'edges .of'which'are'located directly adjacent to the opposite sidesof-the annular channel. Undercut buckets 14, disposed in tandemrelation, are formedin the peripheralzportions of. the wheel and haveperipherally-opening inlet-mouths 14*, that are located between theflanges 13." The-buckets are formed with endwalls 15*, side walls 16*,and bottom walls 17 They arefurthermore provided with laterally-arrangedflared discharge-outletsl5, which incline rearwardlyandnopen through theopposite sideszof the wheels, the mouths. thereof being'fiared, asashownparticularly in Fig. 4 and designated 18*.{It will furthermore be notedthat the discharge-outlets -15 alternately open on opposite sides .ofthe wheel for the reasons hereinafter given, and their inner :ends' areof .less

width thanthelength ofthe pocket-walls through which they pass, asclearly illustrated in Fig. 4

Stationary hub-sections 16 are carriedby the end walls 10 ofthe casingand surround the shaft 8 on-opposite sides'of the wheels saidhub-sections being preferably spaced from the shaft and havingwater-outlet openings 17 in theirlower sides. "Theiinnerends rovided ithi cutjacent to the opposite side faces .of the wheel and parallelthereto, but preferably's 'aced a slight distance therefrom. The dis s18have their eripheries located inside the discharge-out ets 15 of thebuckets and in spaced relation to the walls of thecasing.

Water is supplied to the motor from a pipe 19, having a semicircularportioneZO, extending partially around and in spaced rela'tion to ,thewall-9 of said casing. Nipples 21., ar-

ranged on the inner side of the semicircularportion 20 of thesupplyipe,have threaded thereinto couplings 21*, t at are alsothreadedintounions 22*, connected tonozzles 22, formed in the wall 9 ofthe. casing,- the .nozzles projecting through the outstanding nipples.23 of saidcasing into the annular channel and alined with the 1 space.between the flanges '13 of the wheel. Valves 24', arranged i nthecouplingsbet'ween the pipe ZO and: the

wheel-casing, controhthe supplyof .water through said nozzles. Theoutlet forrthe discharged water is through.the'bottomv of.- the casingby .means of a suitable discharge=pipe 25, and vent-nipples 26, locatedin the upper portion of the casing, prevent the formation of a vacuumtherein.

Water is supplied to the pipe 19 through any suitable head, which mayhave any pressure desired. This water will thence pass into the pipe 20,and consequently through 'the nozzles 22, the amount being regulated bythe valves 24. The water will be projected from said nozzles into thebuckets 1 1 and will escape therefrom on opposite sides of the wheel.This alternate discharge on opposite sides will preventthe end thrustuponthe shaft-a very important feature in a wheel of this character. Thewater discharged from the buckets will be projected over the guards 18,and thus be kept away from the side faces of the wheel, finally passingout through the tail-pipe 25. In like manner the portions of the shaftlocated within the casing will be protected from the discharging water,and frictional resistance therefrom is avoided to a very materialdegree. The small quantity of water that does find its way between theguards 18 and the wheel will readily escape through the openings 17.With this structure, therefore, it will be seen that not only is endthrust prevented, but frictional'resistance is greatly reduced.Moreover, the construction is simple and the wheel may be cast in onepiece, giving it plenty of driving weight.

It will be clear that the structure can be readily dismembered and thataccess can be other.

the invention is embodied in the form of a roeasily gained to thevarious parts. 1 This is 35- particularly true of the nozzles andsupplypipe, which are located eXteriorly of the casing, so that thevalves are conveniently arranged, and each nozzle is independent of theIt will of course be understood that the wheel and water-supply can beduplicated for the purpose of securing additional power, this lattertype of wheel being especially adapted to low heads of water havingconsiderable volume of flow.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape,

' proportion, and minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention. In this connection and at this point itmay be statedthat while tary impact-motor there are features thereof which areundoubtedly capable of advantageous use in connection with turbines.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is '7 1. In a hydraulic motor, a wheel havingspaced peripheral flanges, pockets having closed bottoms, andinlet-mouths located between the flanges, each of said pockets be ingprovided with a single lateral rearwardlyinclined and outwardly-flaringdischarge-outlet that opens through one side of its pocket, said outletsopening alternately on opposite sides of the wheel.

2. In a hydraulic motor, a wheel having a peripheral series of undercutpockets disposed in tandem and having peripherallyopeningreceiving-mouths, and end, side and bottom walls, the pockets of saidseries each having a single rearwardly-extending outwardly inclineddischarge outlet opening through one of the side walls of the pocket andof less width than the length of the pocketwall through which it passes,said outlets flaring outwardly.

3. In a hydraulic motor, the combination with a casing comprising anannular wall and end walls detachably secured to the opposite edgesthereof, of a shaft extending across the casing through the end walls, awheel mounted on the shaft in spaced relation to the end walls andhaving a peripheral series of b uckets provided with outlets through thesides of said wheel, means for supplying motive fluid to the bucketsthrough the annular wall, hubsections carried by the end walls anddetachable from the casing therewith, and guarddisks carried by theinner ends of the hubsections and located on opposite sides of the wheeldirectly adjacent thereto, said disks terminating short of thedischarge-outlets and being removable with the end walls andhub-sections.

4. In a hydraulic motor, the combination with a casing comprising anannular wall and end walls detachably secured thereto, of a shaftextending across the casing through the end walls, a wheel mounted onthe shaft within the casing and having a peripheral series of bucketsprovided with inlets arranged inside the annular wall and with dischargeoutlets opening through opposite sides of the wheel, a supply-pipeextending about the annular wall exteriorly thereof, a plurality ofnozzles connected to the supplypipe and the annular Wall and projectingthrough said annular wall and terminating short of the wheel,hub-sections carried by the said end Walls and removable therewith, saidhub-sections surrounding the shaft on opposite sides of the wheel andhaving wateroutlets in their lower sides, and outstanding guard-diskscarried by the inner ends of the sections and located on opposite sidesof the Wheel directly adjacent thereto, said. disks terminating short ofthe discharge-outlets and being removable with the end walls.

5. In a hydraulic motor, the combination with a casing having an annularwall pro vided with an annular recessed channel in its inner side, of ashaft, a wheel carried by the ITO channel, buckets formed in theeripheral portion of the wheel, said buckets aving inlet-openingsbetween the flanges in line with the recessed channel and having outletsopening through the sides of the Wheel, a supplypipe ,surrounding'theannular Wall exteriorly thereof; and a plurality of nozzles connected tothe pipe and extending through the annu- IO my own I have hereto affixedmy signature in the presence of two Witnesses.
